PowMr 100A 300A Battery Tester Voltmeter Ammeter Power Voltage

PZEM-015: Measuring Range 300A (use external shunt, can matched with 50A, 100A, 200A, 300A four kinds of shunt).

Function description:


Measuring range: 0-60000W

Display format: < 10W display as: 9.99W

< 100W display as: 99.9W

< 1000W display as: 999W

< 10000W display as: 9.99kW

≥ 10000W display as: 19.9kw

Minimum resolution: 0.01W

The starting test power: 0.2W

Measurement accuracy:1%

Internal Resistance:

Internal resistance= (Full voltage – Bring load voltage) / Bring load current, when the bring load voltage is larger than the maximum voltage, the internal resistance is zero.

Measuring range: 0-999 milliohm

Display format: 999 milliohm , when over the test range or the current is zero, it display “—“.

Minimum resolution: 1 milliohm

Measurement accuracy:1%


Before you test the internal resistance, you should preset the full voltage depend on the battery type, after it is fully charged youcan use it to test;

if you do not fully charge it, you can set the battery without load voltage is the full voltage, then test; the internal resistance is not a fixed value, the more the battery discharged, the bigger the resistance.


Measuring range: 0-1000AH

Display format:

< 1AH display as: 999mAH

< 10AH display as: 9.99AH

< 100AH display as: 99.9AH

< 1000AH display as: 999AH

Minimum resolution: 1mAH

Measurement accuracy:1%


Battery capacity testing is a cumulative process of discharge current versus time, it need some time, the time is depend on the discharge current;

Before you test the capacity, you should preset the full voltage and the cut-off voltage depend on the battery type, after it is fully charged you can use it to the discharge test; When the dump energy display blank, it means the discharge is over, this capacity display value is the battery’s capacity.

Dump energy:

Dump energy is display via the battery symbol, totally 10 grids, every grid present 10% energy.

Dump energy is calculated via the current battery voltage value, before test you should preset the full voltage and the cut-off voltagedepend on the battery type;

every grid voltage = (the highest voltage – the lowest voltage) / 10.

Accumulate energy consumption:

Measuring range: 0-9999kWh

Display format: < 1kWh display as: 999Wh

< 10kWh display as: 9.99kWh

< 100kWh display as: 99.99kWh

< 1000kWh display as: 999.99kWh

≥ 1000kWh display as: 9999kWhOver the test range will become zero.

Minimum resolution: 1Wh

Measurement accuracy:1%

Note: 1Wh=0.001kWh=0.001 Kilowatt

Running time:

Measuring range: 0 ~ 999 hour (without load the time will not accumulate)

Display format: 0:00:00 ~ 999:59:59

Over the test range will become zero.

Operating Instructions:Setting the full and cur-off voltage

Package included: 1 * DC Multimeter Battery Tester Monitor
